Application November 21, 1950, Serial No. 196,852

, 1 Claim. (01. 16-30) The present invention relates to shiftable coasters for furniture and has reference to the broad category of fiat bottomed glass and similar cups used as receivers for furniture legs with or without casters and which are chiefly employed to permit furniture to be slid and thus shifted from place to place without marring highly finished floors and floor coverings such as linoleum and the like.

One type of coaster which is often seen in use is in the form of a heavy or durable glass cup with a flat discal bottom and a concavity forming a seat for a furniture leg, such as the leg of a bed, heavy table or the like. In recent years tubular metal legs which are bent into various forms and styles of frames for tables, chairs and the like, especially on porch furniture, have come into great popularity and are in Widespread use. Also, asphalt tiles and linoleum and similar floor coverings are as popularly used as ever but are often subject to indentations and are marred by marks when tubular legged furniture is rocked, slid or otherwise moved over a compressible floor covering. There has therefore existed, knowingly or not, a great need for a coaster which serves as a satisfactory glide and fioor surface protector. It is therefore the object of the present invention to provide a plastic or equivalent coaster which is simple, economical and which lends itself to fulfilling the requirements herein under advisement.

Another object of the invention is to provide a coaster which, being expressly made for particular purposes will comply with the needs and requirements of manufacturers and users alike.

More specifically, the invention has to do with a coaster of plastic or equivalent material which is of requisite rigidity and which lends itself aptly and admirably well to serve as a glideable base for tubular furniture legs wherein U-bends, V-bends and the like define an elbow which, if left to prod the floor covering damages same and produces objectionable marks.

Briefly summarized, the coaster is in the nature of a substantially rectangular plastic block having a flat bottom and suitably shaped marginal walls and having a concavity in its top which is semi-circular or substantially so, so that it provides an adequate and reliable seat for the elbowbend of a tubular leg structure, fastening means being provided for separably joining the coaster with the coacting elbow-bend.

Other objects and advantages will become more readily apparent from the following description 2 and the accompanying sheet of illustrative drawings.

In the accompanying sheet of drawings wherein like numerals are employed to designate like parts throughout the views:

Figure l is a fragmentary perspective view of a portion of a tubular furniture leg showing the elbow-bendand showing the coaster detachably connected to the latter;

Figure 2 is a section on an enlarged scale taken on the plane of the line 22 of Figure 1, looking in the direction of the arrows; and

Figure 3 is a perspective view of the coaster per se.

Referring now to the drawings and particularly to Figure 1, the numeral 4 designates a leg structure which, as before stated, is an aluminum or equivalent tubular leg construction having a U-shaped or V-shaped portion and defining complemental portions or branches 6 and 8 joined by a somewhat rounding bend or so-called elbowbend 10. Usually, if this sort of a bend rests for any length of time on a compressible floor covering it will form an ugly identation in the surface of the latter. On a highly polished floor it is apt to smear and mar the floor particularly if it is moved in relation to the floor surface. In many instances cup-type coasters are used on ordinary and especially heavy furniture pieces. This accounts for the provision of the coaster shown in Figure 3 which is denoted generally by the numeral l2 and is in the form of a rectangular or equivalent glass or commercial plastic block. It has perimeter or marginal edge portions and a fiat bottom M which may be used for gliding or sledding the coaster in the well known manner. The upper surface is formed with a semi-circular concavity l6 providing a seat for the knee or bend ID. The central portion of the block is provided with appropriately sized passage or bore l8 having a counterbore 20. These bores serve to mount and accommodate a rivet with a head portion 22 lodged in the counterbore and a shank portion 24 in the main bore with the shank extending through and beyond the bore and terminating in curvate spring clips or fingers 26. These are adapted to pass through and be retained in an opening 28 provided therefor at the vertex of the bend or elbow I0. This clip equipped rivet provides a satisfactory ways and means of separably joining the coaster to the bend of the leg construction in an obvious fashion. It is believed to be within the purview of the invention, however, to permanently attach these types of coasters on tubular leg constructions. Therefore,

the invention is believed to reside in the combination shown in Figures 1 and 2 on the one hand, and in the subcombination or article per se as depicted in Figure 3 on the other hand.

A careful consideration of the foregoing description in conjunction with the invention as illustrated in the drawings will enable the reader to obtain a clear understanding and impression of the alleged features of merit and novelty sufficient to clarify the construction of the invention as hereinafter claimed.

Minor changes in shape, size, materials and rearrangement of parts may be resorted to actual practice provided no departure/is ade from the invention as claimed.

Having described the inventiongewhat is claimed as new is: r

For use in supporting and sfiiftilfig porch furniture of a type having tubular legs Wheteim each leg embodies diverging branches defining a substantially V-shaped elbow; aglider-type coaster adapted to be interposed between the floor surface and said elbow-to prevent the latter;

from marr ing the: floor surface and to permit the furniture to be bodily slid from place to plac over the floor surface, said coaster comprisin a' one-piece block having a flat smoothv bottomto glidably contact andsled over the floor surface, the top of said block having an open-ended semicircular groove providing a, seat to conformably accommodate the V-shaped elbow, said block being provided with a centrally disposed vertical bore adapted to register with a hole in said elbow, the lower end of said bore being provided with a counterbored portion, and a readily insertable and removable snap-type rivet having a head fitted into the counterbored portion and the stem projecting upwardly through and beyond the vertical bore, the upper end of said stem being provided with resilient assembling and retaining" fingers cooperabfe witha; hole provided therefor in said elbow.
